Young Heroes: Returning to the Past to Change the Ending

[Transmigration + Reborn + Misunderstandings + Everyone's Darling + No Romance + Healing Regrets! An An's identity will remain a mystery for a while, drawing speculation from all sides! As for when her true identity is revealed... take a guess!] My name is Xiao Anyu. I was born in the tenth year of Chonghe, the only daughter of Xiao Chuhe, Prince of Yong'an, and Sikong Qianluo, the Vermilion Bird Envoy! Actually, I wasn't originally from this world. I came from the modern world of the twenty-first century, but one day, for no apparent reason, I turned into a baby. I couldn't even understand what the people here were saying. Just as I was panicking, something calling itself the System appeared. It told me that, due to its mistake, I had already died in the modern world, and that it had been sent by its master to keep me company! Well, dead is dead. I had no ties there anyway, and nothing worth longing for. Besides, here I have a family who loves me. Even though I was born frail, it's still much better than life over there! As for why I was born frail, it was because in the tenth year of Chonghe, while my mother, Sikong Qianluo, was still pregnant, she was harmed by villains, causing me to be born prematurely. That's why I was so weak from birth! Because of what happened, I was doted on from the moment I was born. If I asked for the stars, they wouldn't give me the moon instead. They were afraid I might break if they held me in their mouths, and afraid I might fall if they held me in their hands! That's also why my father named me Xiao Anyu, with An'an as my nickname. He wished for me to live my whole life in peace and safety, carefree and content! I thought I could stay carefree forever, but a sudden conspiracy brought disaster upon everyone! I wasn't willing to accept that outcome, so I sought out the System and returned to my father's era. I want to change how things end!
